MANET network is a type of de-centralized network and is high vulnerable network which requires secure communication. A significant security issue in MANET is to protect the network layer from malicious nodes that misbehaves often to obtain the data that is not broadcasted for them i.e. gray hole attacks aka selective forwarding attack that leads to Denial of Service attack (DoS). In this paper, the overall objective is to find the nodes which frequently misbehaves and based upon their miss ratio they will be eliminated from the network.
